Fantastic entry! Looks great, sounds great and plays great. The puzzle mechanic was quite fun once I figured it out.
Does the game just loop back to the start when you win? Just wanna make sure I didn't miss anything...
The theme connection was a bit thin for me - I guess sleep is essential?
This was one of the few entries that I felt wasn't harmed by diversifiers but perhaps made better by them, so kudos for that!
